    Impact of noise on European mink (Mustela lutreola) behaviour
    (Eesti Maaülikool, 2025) Zarja, Aleksandra; Arney, David Richard (advisor); Nemvalts, Kristel (advisor); Kiik, Kairi (advisor)
    Due to increasing urbanisation, the impact of noise on living organisms can be a major welfare issue. It has been shown that anthropogenic noise can cause health problems in many animals. Particularly important is to define the impact of noise to endangered species such as the European mink, whose wild population survival is highly influenced by the successful reproduction of the captive population, which in turn is influenced by the environmental conditions of artificial environment. The aim of this bachelor's thesis was to examine whether noise exposure during public events affects the behaviour and activity patterns of captive European mink. This research was conducted on 14 adult male European mink. The observation period was divided into four nights before the event (control period), two nights during the event (high noise period), and four nights following the event (recovery period). All analyses were performed within the RStudio environment, using a linear mixed model. The results indicated that stereotypic behaviour decreased significantly during noisy event. Total activity declined in the days after the event. Accordingly, the event had a significant delayed impact on the activity, and it suggests that noise exposure not only decreases movement in general, but it could also inhibit adaptive behaviour by temporarily suppressing stereotypical behaviours. The obtained results provide a foundation for future research on the European mink.
